CROSS-REFERENCE TO RELATED APPLICATIONS

This application is a continuation-in-part application of U.S. patent application Ser. No. 14/942,126, entitled System and Process for Generating an Internet Application, filed Nov. 16, 2015, pending, which claims priority to Australian Provisional Patent Application No. 2015903445, filed on Aug. 26, 2015, both of which are fully incorporated herein by reference.

TECHNICAL FIELD

The present invention relates to a data transformation system. More particularly, the present disclosure relates to a spreadsheet converter for generating an output suitable for use with an internet webpage.

BACKGROUND

Spreadsheet applications for computers have become commonplace in an office or business environment. Spreadsheets are generally used to perform a number of numerical analysis or calculations based on function entered into the spreadsheet. Typically, a spreadsheet is used to generate a graphic or image, such as a graph for data sets. While spreadsheets provide a versatile means for reporting there are a number of difficulties associated with displaying spreadsheet data, particularly graphs, on interactive websites or online platforms. Further difficulties arise when attempting to generate an interactive graph or use data associated with an equation contained within a spreadsheet for online applications.

Software applications currently exist which can convert a spreadsheet data into a suitable programming language such as hypertext markup language (HTML), JavaScript, css and other machine language code. However, to convert this data into a suitable internet format which typically takes a significant amount of time coding, which can be days to months of time, and is generally very costly and heavily reliant on the complexity of the data in the spreadsheets, particularly with respect to interactive graphs or complex equations. In addition, these applications do not allow the use of embedded data without significant manipulation into a coding format compatible with standard internet formats, such as HTML.

HTML is commonly used to generate a website with a basic structure including headings, paragraphs and other elements such as images and tables. However, converting spreadsheet data into a HTML format requires a significant amount of time and expense. In addition, generating HTML script or code based on data from a spreadsheet does not allow data to be readily transferred back into a format suitable for entry into a spreadsheet document. As such, if data is altered, modified or added during HTML coding, a user must also manually add the new data in a format which is compatible with the spreadsheet, and vice versa. This may generate a significant amount of double handling for an organisation which can be costly and consume a significant amount of time.

Further, formatting data for output on a digital display can be difficult and commonly results in misaligned or visually displeasing formatting. This can lead to bad user experience with an application or website and user dissatisfaction. In addition, the prior art does not typically allow for higher processing functions of converted spreadsheets, such as realtime graphic of functions or interactive graphs or tables.

Other common internet formats to which text is converted includes; JavaScript, W3C, direct markup language, Web Application Description Language (WADL), or any other suitable internet/web language or code. These coding formats also have substantially the same problems associated with the spreadsheet compatibility and conversion of data expenses and time constraints.

Other issues and time delays can arise when converting a spreadsheet for webpage viewing, and even more so when adapting data for an application to be viewed on multiple device display sizes. Developing a webpage or application which can automatically alter or move the elements on a page or display a webpage or application with a dynamic display based on the orientation of a device can take a considerable amount of time and is a significant cost for a new website or application. This is exacerbated with the need for web applications or websites to alter the size of the output for varying display sizes. More particularly, there is a significant amount of coding required to adequately display a webpage on a cellular or mobile device such as a smart phone.

Any discussion of the prior art throughout the specification should in no way be considered as an admission that such prior art is widely known or forms part of common general knowledge in the field.

DESCRIPTION OF THE INVENTION

Preferred embodiments of the invention will now be described with reference to the accompanying drawings and non-limiting examples.

In a broad aspect, the present application is directed towards a system and process for converting a spreadsheet into Extensible Markup Language (XML), or an XML derivative, such that it may be used to generate an output suitable for viewing on a display device. XML is a markup language that defines a set of rules for encoding documents in a format which is both human-readable and machine-readable. It is defined by the W3C's XML 1.0 Specification and by several other related specifications, all of which are free open standards. Preferably, the output is an internet or online application, such as a website, a webpage, a web interface, a smartphone or a tablet interface or any other suitable online format which can preferably be hosted by a web domain. The system may be adapted to provide a compatible output for exiting HTTP architecture of the internet.

Generally, the spreadsheet comprises ‘data-intensive information’ which may comprise a number of calculations, such as formulae, graphics, images or charts. A spreadsheet is a desirable format which is adapted to organise information to at least one of create, generate, view, edit, track, manage and/or maintain the data-intensive information. With the proliferation of computer technology and the commonality of computer devices, an internet application has become a preferred way of allowing consumers to interact with data-intensive information. Interacting with the data-intensive information can include consuming the information, allowing consumers to create other value-added information or alter the data-intensive information.

Preferably, the system or process is adapted to transform the data-intensive information stored in a typical spreadsheet into an internet application. Any suitable interface may enable content owners to author or generate data-intensive information in a spreadsheet, and display the data-intensive information to consumers for consumption as an internet application. Preferably, the data-intensive information as perceived by a content owner in the form of a spreadsheet is equivalent to the data-intensive information displayed to a consumer in the form of an internet application. As such, there is no loss of data between the spreadsheet and the internet application, however the content owner can restrict access to data or hide predetermined data sets from a consumer. Further, not every data set from a spreadsheet is required to be used to generate an internet application. For example, the content owner may only assign a single data set from a spreadsheet to display to a consumer.

The data-intensive information associated with the internet application can be translated back to the spreadsheet, or a further spreadsheet, such that the data is bidirectional. This allows information from either the spreadsheet or the internet application to be optionally translated to the other respective format (i.e., information from the internet application is translated to the spreadsheet, or vice versa). This allows an equivalent data set or at least a portion of the data-intensive information to be easily translated between a spreadsheet and an internet application which is not possible using html coding or other commonly used coding methods as the data cannot be converted into a format suitable for a spreadsheet. When information is presented in the form of an internet application, it can be adapted for display to end-users in a variety of devices (e.g., portable devices) and formats (e.g., different viewing device screen size).

Referring to FIG. 1 , there is depicted a simplified embodiment of the system 10. The system 10 is adapted to receive a document or spreadsheet 20 and store the document on a server or storage device 30. The document 20 can be uploaded by a user, company or client with authority to upload a document to the system. In at least one embodiment, the server 30 is a data repository which stores at least one data set, which is preferably stored in a database. The server 30 can be a non-volatile memory medium, a cloud or any other suitable computer readable medium for storing electronic documents. The spreadsheet 20 may be in a standard spreadsheet format such as; .gnumeric, .ods, .xls, XMLss, comma-separated values, CVS application support, Data Interchange Format, Symbolic LinK (SYLK), Tab-separated values or any other spreadsheet format, which may include a derivative of any one of the previous formats. Another common spreadsheet format is “.xls” used by Microsoft Excel™. It will be appreciated that the system can be adapted for use with other known spreadsheet formats.

The server 30 is adapted to be in communication with at least one user device 40 which can access the server 30. The device 40 allows a user of the system to interact with at least one file, document or spreadsheet 20 associated with the server 30. The system may further allow a user to interact with a client profile or a template associated with the system. When a user interacts with the spreadsheet 20, a copy spreadsheet 21 is uploaded to, or displayed on, the user device 40. The copy spreadsheet 21 is isolated from the original spreadsheet 20 stored by the server 30. Isolating the copy spreadsheet 21 from the server 30 allows an ancestor document to be generated if changes are made to the spreadsheet 21. This allows changes which are made to the copy spreadsheet 21 to be isolated from the original spreadsheet 20. If changes are made to the copy spreadsheet 21, and the copy spreadsheet 21 is saved, the original document 20 becomes an ancestor document 20A and the copy spreadsheet 21 becomes the newest document 20.

Preferably, the system 10 retains all previous documents uploaded or saved by the system, and may allow a user to access an ancestor document 20A instead of the document 20. For example, if a copy spreadsheet 21 of a spreadsheet 20 is uploaded to a user device 40 and at least one change is made to the copy spreadsheet 21, the copy spreadsheet 21 is saved by the system as the newest spreadsheet 20 and retains the original spreadsheet 20 as an ancestor document 20A on the server.

Optionally, the system may then access at least one of the spreadsheets 20 or 20A, or any other predecessor or ancestor spreadsheet document associated with at least one of the spreadsheets 20, 20A.

It will be appreciated that a document 20 or spreadsheet family may be created upon uploading a spreadsheet 20 to the server 30. A family identifier or family number may be associated with a document 20 which may allow a user to easily identify a particular document. For example, the system 10 may have a user associated with five hundred families stored on the server, with each document corresponding to a different webpage or application, and the user requests to access family forty-six to edit a predetermined webpage. This allows the user to easily find the correct document without searching for extended periods of time. A family identified can be manually assigned by a user, or may be automatically assigned by the system 10.

The system 10 may further allow at least one of; merging of documents 20 associated with the server 30, viewing of multiple documents 20, or generating a mark-up copy of a document in which changes made to a first document relative to a second document 20 can be viewed by a user. Any mark-up changes can be generated while editing a copy document and may be assigned a user identifier, such that marked-up or edited data can be easily associated with the user who edited the document. In an embodiment, a mark-up view may be generated for a copy document 20A relative to an ancestor of document 20A when the user generates the copy document 21. It will be appreciated that if the system 10 is adapted to view or compare multiple documents, the documents are not required to be from the same family, but preferably include at least one matching data set. Optionally, merging documents generates a document with a plurality of tabs or pages, in which each page or tab contains one of the merged documents.

As shown in FIG. 3 , the system is adapted to generate an ancestor document chain or family document chain (herein referred to as a “document chain”). A document chain is generated when an original document 20 is uploaded to the server 30 and a user generates at least one new or modified document 21. A document chain may allow a user working with a document 20 to view and/or make a copy spreadsheet 20 which has previously been stored by the server 30. The copy spreadsheet 20A may form the newest document in the document chain such that if at least one further copy 20AA (not shown) is generated, the system can access an earlier version of the document if there is an ancestor document 20A. If a user has generated a copy 21 and reverts back or accesses a previous document 20A, a new copy spreadsheet 20B (not shown) is generated which may start a fork in the chain. If a fork in the chain is generated, documents 20A and 20B (not shown) may be isolated from one another respectively, but still have the same common ancestor document 20A. It will be appreciated, that more than one fork may be generated along a chain. Obsolete forks or discontinued forks in document chains may have restricted access or may be locked, such that a user cannot generate an editable copy of the document without authorisation or a password.

Optionally, a user may assign a key, an authority signature, a lock or any other security feature to a document to prevent unauthorised persons from editing or altering a document 20. This may include cryptographically securing an account or document 20 associated with the system 10. Cryptographic securities may be, for example, a cryptographic algorithm or hash function.

While the system 10 is preferably adapted to allow access to ancestor documents 20A, a user may be required to have authorisation to access at least one ancestor document 20A. An ancestor document 20A may be date stamped or be associated with at least one data set which may identify a user of the system who created the document or edited the document. The document may further be assigned mark-up changes or a viewable record of modifications, such that if a user accesses an ancestor document 20A they may compare the ancestor document to a relative document, associated preceding document or the current document 20 stored on the server 30. Further, an ancestor document 20A can be locked at a predetermined length. For example, the system can be adapted such that an ancestor document 20A in a document chain can be locked when it is the fifth document from the newest document.

Referring now to FIG. 2 , there is illustrated an embodiment of a process adapted for use with the system 10 for generating an output. At least one document 20, or more preferably a spreadsheet, is uploaded and stored by the server 202. The document 20 may be stored for a predetermined period of time, for example the length of a subscription to use the system, a second, a plurality of seconds, minutes, hours, days, weeks, months, or any other predetermined period of time. A document 20 may be assigned an expiry date or a locking date, which can delete it from the system or lock the document from being edited. It will be appreciated that at least one authorised user of the system has authorisation to unlock or lock a document.

The user selects a render interface or a render template 204 from the server or uploads a rendering template 25 compatible with the system. The rendering template 25 can be a wireframe or other web page template 25 which can be assigned data by the system 10. At least one document 20 or ancestor document 20A is selected by the user via a user interface or user portal 206. In this embodiment, the document is a spreadsheet comprising at least one data set. A data set from the spreadsheet can be assigned or rendered to the rendering template, and more particularly to a selected element of the rendering template 208. Simultaneously, as the user edits a document or a spreadsheet, a copy of the document in XML format is also edited to record the changes. It will be appreciated that at least the copy document 21 and the XML format of the copy document will comprise substantially the same data sets. Hence, the user can choose to edit the spreadsheet or the template, or add additional data 210. If the user edits the data, either in the template 25 or the spreadsheet, the data in the respective other will be also edited to reflect the changes made in the template 25 or the document. The bidirectional editing of the document and the template 25 cannot be performed with script or code as the data. This is due to the script or code requiring significant editing or rewriting to be in a format suitable for a webpage which results in the script of code not being in a suitable format for a spreadsheet.

In at least one embodiment, the system 10 is adapted to display changes or edits in realtime, such that the user can view changes made in the template 25 and/or the spreadsheet simultaneously. It will be appreciated that changes can be reflected in the spreadsheet, the XML spreadsheet and the template 25 simultaneously. The template 25 may further display an anticipated output to the user, such that a user does not need to generate a final output to view how data looks applied to a template, for example an internet webpage or internet application may be displayed to a user. This can reduce the time required for a user to generate a webpage or other output for an internet or other electronic application.

The system can be adapted to load a copy spreadsheet 21 of spreadsheet document 20 to a user device 40 and isolate the copy spreadsheet 21 from the original spreadsheet document 20, such that changes made to the copy document 21 are not recorded in the original document 20. More than one document 20 can be loaded by a user such that multiple documents can be used to generate at least one output. If multiple documents are required to generate the data for the template, the multiple documents can be optionally merged into a single document. Alternatively, the template 25 may source data from multiple documents from different families and save each document as a new fork or the newest document in a document chain.

After the selected data sets have been assigned to the template 25 and any optional edits have been made, the user can update interface values 212 or assign any optional rules to the template. Rules can be used to display data in a desired manner or in a particular predetermined format. Preferably, the template 25 is assigned at least one rule with respect to how to display elements or data for different display devices. For example, a rule can display the elements on the template 25 to a user in a predetermined manner for a laptop device and can display elements in a secondary predetermined manner for a smart phone device. This functionality generally requires a significant amount of coding in previously known systems to generate a desired output; however, the rules assigned to the template 25 may avoid delays and difficulties with generating outputs with varying sizes.

Once all of the desired rules have been assigned to the template 25 or the data assigned thereto, the template 25 passed through an aggregator 214 (which may also be referred to as a render interface) to generate an output 216. The output is preferably a webpage or comprises a plurality of webpages to generate a website, or may be an internet application. If more than one webpage is required, the system may merge or aggregate a number of data sets and/or templates to generate multiple webpages. Other outputs from the system can include; PDFs, spreadsheets, slide show presentations, document files or any other predetermined output. Preferably, the output generated is in a format suitable for displaying as a webpage.

The output can comprise interactive features, such as audio, video, interactive graphs, input fields, dropdowns, lists, or any other predetermined interactive feature. The features are generated from the data assigned to the template 25 from the at least one spreadsheet.

The aggregator can be a runtime application which renders the selected data into the template. The runtime application can be associated with at least one rule or modifier which can manipulate data during rendering of the data into the template. As a wireframe typically lacks typographic style, colour, graphics or other stylised elements, rules may be used to define these features within the template. Preferably, a predetermined threshold is triggered by at least one data set highlighted within the spreadsheet. Triggering a predetermined threshold may be caused by at least one of; a data set exceeding a predetermined value, a missing data set, an incorrect data set, an incomplete data set, a document format, a data format or any other value which may be exceeded. It will be appreciated that a rule may assign any predetermined attribute to a data set or a rendering template 25 to produce a desired output 55. Optionally, a report can be generated if there are any errors with rendering the template 25 or generating an output 55. The report may comprise instructions or suggestions on how to remedy or solve errors or problems with at least one data set.

Preferably, the output 55 is webpage adapted to dynamically resize or move elements in the output 55 based on the display device used by a viewer of the output 55. For example, the output 55 may be different for a user of a computer and the user of a smart phone. It will be appreciated that resizing the webpage for different devices may add, remove, restrict or limit the information displayed to a user based on the device. For example, if the output 55 is resized for a smart phone, elements of the page may be excluded or simplified to produce a more user-friendly interface.

In yet a further embodiment, if a desired output 55 cannot be generated, the system generates a diagnostic or analysis report. The diagnostic or analysis report can provide advice to a user or assess at least one data set assigned to the template. This may allow a user to easily identify errors with output generation and remove the errors to successfully generate an output 55. The diagnostic or analysis report can also be generated with suggestions on how to improve a template 25 or an output 55 generated by the system. For example, if the system determines there may be a more user-friendly method of displaying data, a recommendation may be provided to the user.

In yet another embodiment, an XML format document is generated based on the original format document only when the original document is saved or a template 25 is to be rendered with at least one data set. This may avoid unnecessary XML format copies of a document being stored by the system and may reduce the rendering time for a template. Further, producing an XML document only during generation of the output may further reduce the processing time or reduce the processing power required for generating an output 55.

Data sets can be selected from the spreadsheets by selecting elements or cells within the spreadsheet and applying a matching association with an element within the rendering template. For example, a cell is selected or ‘highlighted’ and an element on the rendering template 25 is matched or associated with the highlighted cell. The data within the cell is then copied into the template 25 from the highlighted cell, which may include formulas, equations, algorithms, embedded data, graphs, charts, flow diagrams, images, audio, video, text or any other dataset assigned to a cell. Preferably, the data uploaded to the template 25 is taken from the XML format spreadsheet. It will be appreciated that the user may assign cells from the original format document, and the corresponding cell in the XML format document can be assigned to the template.

Highlighting a cell or data set preferably applies a viewable marker to a user, such that the user can visually identify which data is selected for rendering into a template 25, used for an output or used for another predetermined output 55. The viewable marker may be at least one of; bolding text, changing a text colour, changing a cell colour, applying a border to a cell, stylising font, or any other predetermined marker to allow a user to determine a difference between a highlighted cell and a non-highlighted cell. This provides a means for a user to ensure that only desired data is selected for an output 55.

In the context of this specification, an output 55 can be at least one of; a word document, a spreadsheet, a webpage, a website, a code, a script, an application, a PDF, a presentation, a slideshow, a report, or any other predetermined output. A document can be referred to as a spreadsheet.

Referring to FIG. 3 , there is depicted another embodiment of the system. The system 10 adapted for allowing a spreadsheet to be uploaded to a storage medium. The storage medium is associated with a server which is adapted to communicate with at least one user device. A communication module or transceiver (not shown) allows communication between the server and at least one user device. A user interface or portal can be displayed on the user device which allows a user to interact with a portal of the server. The portal or user interface may be run from an online portal or via an application (app). Through the user interface, the user can interact with at least one stored document and/or a client profile. The document is stored in at least one database associated with the client profile, and the system comprises a further database which stores at least one rendering template. The rendering template 25 can also be associated with a client profile, or can be publicly accessible by users of the system. The at least one database on the server can segregate documents or other data which relate to a client profile. Segregation of documents can allow family members to be generated. In this embodiment, a document is a spreadsheet document, such as a Microsoft Excel™.

Additionally, the user may manually divide or segregate documents or portions of a document into groups or into individual elements. For example, a single document may comprise all data relating to a company across multiple divisions or departments. As such, the system may separate the data into divisional or departmental sections such that each department can have restricted access to departmental data alone. Segregating documents may provide a database which can be searched or filtered. A client profile can further include information relating to a company, a user or a business. Examples of information include; a business name, a compilation of authorised users, authorised user access levels, contact details, private details, an address, a phone number, email address, a contact person, or an IP address of at least one authorised user. Other personal information or identifying information can also be optionally assigned to a client profile.

The system is optionally adapted to process and analyse a spreadsheet uploaded or associated with the server. Analysing the spreadsheet can identify data or data sets stored in the spreadsheet. The spreadsheet may comprise raw data, formulas or equations associated with at least one cell. The spreadsheet, or at least a portion of the spreadsheet, can be converted by the system and stored in a XML format. Alternatively, the user can select and assign data to be converted into a XML format. This allows only a portion of a document to be converted and can reduce the storage demands of the server 30.

Converting a document format has a number of advantages over writing data into script or code. More particularly, data with macros, visual basic, VBA code, equations, embedded programming or any other functions or data, assigned with a spreadsheet, can be used to generate an output 55 and are not lost during formatting into XML. In contrast, scripting or coding the data from a spreadsheet can result in lost data or require data to be manually entered into another format which may take a significant amount of time. Further, scripting or coding the data within a spreadsheet may commonly cause a number of significant problems, such as programming errors, lost data, unmatchable data sets, formatting errors or other data errors.

When a spreadsheet is selected a copy of the spreadsheet is generated such that the copy spreadsheet is isolated from the original copy. Isolating the original copy ensures that there is a backup copy which the user may revert to if there are any issues, such as data set corruption or other errors, when editing the new copy.

Once a template 25 and at least one spreadsheet have been selected, data from the spreadsheet can be rendered into the template. Data can be selected from a cell or an element within the spreadsheet and assigned to the template. The data element can be; alphanumeric text, a graph, a chart, an image, a pie chart, a bar graph, a line graph, a column chart, an area chart, a scatter graph or any other illustrative representation of data. The system may further allow an image, audio, a hyperlink or a video link to be assigned to the template. Optionally, data assigned to a graph may also be associated with the template 25 such that a graph can be interactively manipulated by a viewer of an output webpage 56.

To select data to be rendered onto the spreadsheet the user may select a cell and apply a marker. A marker may include; a text highlight colour, a text colour, a format change, a font change or alteration, a font size alteration, or any other marker which may identify to a user data which has been selected to associate with a template. Assigning data sets directly to the template 25 removes the requirement cells of a spreadsheet to be converted into script or code, such as HTML, or JavaScript. The system may provide a simple means for generating elements or data to be displayed on a webpage or a website without turning data into script or code. This can potentially save a significant amount of time. Further, the system allows a user who is not skilled with coding or scripting to generate an output which may be suitable for a webpage, which can save a significant amount of resources.

Once a marker has been assigned to a cell or data set, the data set is assigned to a selected portion of the template. The system then updates interface values such that the data set is rendered to the template. The system can then generate an output based on the updated interface values. The output is preferably a webpage which is adapted to be displayed on at least one display size. More preferably, the output is adapted to be displayed on a plurality of display sizes, for example a computer screen and a portable device screen, such as a smart phone.

While the system is adapted to convert the document into a XML format, the system also retains the original document in the uploaded format. This allows the original document to be stored by the system in addition to the new XML format spreadsheet and ensures a backup is recorded if reformatting or other errors occur at a later time. Preferably, any document stored or converted by the system will continue to be stored as a copy in the format as initially stored. A stored document can be locked by the system such that it cannot be edited. However, if a document is locked a document may be copied to allow edits to be made to the copy of the spreadsheet. A locked document can optionally be deleted, restricted, hidden or assigned a predetermined attribute, by an authorised user of the system with a sufficient user level.

The user may optionally create changes in a document which is in an original format or make changes to a converted document in XML format. In either case the system is adapted to save and store a copy of saved changes in both the original format as well as a XML format. This creates a bidirectional storing of documents which easily allows any edits, modifications or changes made to the converted format document also savable to the original document. Further, the system may be adapted to allow a user to edit data within the template 25 which can relay the same edits to at least one of the XML format document and the original format document.

Bidirectionality is not possible with HTML, or JavaScript or other internet based coding, as the code cannot be easily converted back into a format which is compatible with the original spreadsheet. This is due to script or code formats being incompatible with spreadsheet documents.

There are a number of significant advantages with bidirectionality, particularly the ability to store data in both an original format as well as XML allows a user to easily view any incorrect formulas, equations or data and more easily correct any errors or inconsistencies with a document. Bidirectionality further allows a user to maintain a progression or history of changes made.

In yet another embodiment the system is adapted to store a template 25 with associated data, such that a user may revert back to a previous template 25 which allows easy replacement or update of a webpage. Saving a template 25 may further allow a user to revert to an earlier template 25 or correct at least one error with a template 25 or data within a template 25 without having to remove an active template 25 from a webpage. Further, the system can store a work-in-progress, which comprises of at least one selected spreadsheet and at least one template, such that a user can make amendments or edits for generating an output across a desired period of time or incrementally.

The system may further be adapted to allow multiple templates to be used and merged into a single template 25 for a webpage. In one example, a user can select multiple documents and assign at least one data set from selected documents to a template 25 for rendering. If a user assigns multiple documents for rendering in a single template, the multiple documents may be merged into a new single document, which may be stored both in an original format and as a XML format. If multiple documents are merged, the multiple documents may form a new family or create a link between document chains. While documents can be merged, the system may only generate a new document based on the data from highlighted cells, such that any data not highlighted in the multiple documents, which is not relevant to the selected cells, is not copied into the newly generated document.

In yet another embodiment, the system is adapted to display to a user rendered data in realtime such that a user may view any changes rendered to a template. Viewing changes in realtime can allow a user to view errors or other anomalies within the spreadsheet, which allows a user to correct any potential errors before saving a copy to the storage medium.

When a user generates an output, the system uploads the reporting template 25 with any predetermined rendering rules, associated spreadsheets and highlighted data. Rendering rules can be assigned by a user of the system or assigned automatically by the system depending on an output. Generating an output simultaneously stores a further copy of the document in both an original format and a XML format. The output generated is then further stored by the system.

An authorised user can download an output from the server, display an output on a display device or store an output independently from the system. The output can be adapted to be used for an internet application, an intranet, a webpage or any other digital content. The user may optionally store the output in a printable format such that the output can be stored in a physical medium. It will be appreciated that if a copy of the output is downloaded to another device, the user may not require a connection with the system to interact with or view the document. The user may at a later time re-establish the connection with the server such that the document may be uploaded to the server.

Preferably, the output of the system is adapted to dynamically resize or scale the template 25 based on a user display device. Resizing or scaling the output of the spreadsheet may include adjusting the vertical and/or the horizontal alignment of the page. Further, the output can be adapted to move or resize individual elements on a webpage to generate a format which is more visually appealing or more user-friendly.

The system may further be adapted to compile or merge at least two outputs to generate a web site. The outputs can further be assigned to a layout template 25 which allows outputs to be assigned to elements of the layout template. An element of a layout template 25 can be a webpage with at least one web address assigned thereto. This can allow a complete website to be compiled or aggregated from multiple outputs.

In at least one embodiment, the system may be adapted to convert a spreadsheet into XML or a derivative format of XML, such as XLSX which is a file extension for XML if the original file is a XLS file.

Optionally, the system is adapted to encrypt documents which are uploaded to the server. Any predetermined cryptographic algorithm may be adapted for used by the system, for example a SHA-2 hash function may be used to encrypt the data. Preferably, if the system adopts a hash encryption, the system further comprises a paired key, in which one part of the key is provided to the user and the other key is retained for a matching association by the system. A paired key may be similar to a private and a public key.

In yet another embodiment, the system is adapted to receive a document or output from another application. The application may generate a report document, preferably a spreadsheet, suitable for uploading to the system. The report document generated by the application comprises at least one data set which can be rendered into a template.

The system can be adapted for user subscription. The user subscription can be a multi-tier subscription system in which features of the system are restricted based on the user subscription tier or allowable based on the user tier level. At least two user tiers may be used by the system, in which the higher tier allows access to all of the features of the system and the lower tier subscription restricts a number of features for the user. It will be appreciated that any number of predetermined tiers may be used by the system.

In yet another embodiment, the system is adapted to generate a report document. The system may use the data contained within the spreadsheet to generate the report document. Preferably, the report document is generated with respect to a number of predetermined business rules. The business rules may dictate or influence the generation of the report and the information contained within the report. For example, data contained within a spreadsheet may include a data which may be confidential or private which may be required to be excluded from a report. As another example, rules may be set up to display a spreadsheet data in a summarised graphical form.

In one example, a report can be generated by the system at a management level which contains a detailed amount of information. The user of the system may then generate a report for an employee on a respective lower level, or for a shareholder, which preferably includes a lesser amount of information. The system may allow the user to redact, exclude or modify information displayed with the report for a predetermined viewer.

A user authorisation level can be associated with a user of the system, such that a predetermined user can view only predetermined documents or information. This can restrict confidential data from being accessed by users who do not have sufficient authorisation. An authorisation level can further be assigned a department marker which can further restrict or allow access to documents from at least one predetermined department. For example, if an accounting department marker is assigned to a user, only documents which have a corresponding ‘accounting’ tag can be accessed by the user.

The report generator can extract information from a document as raw data which may then be used to generate a report. Optionally, the system is adapted to extract data from a plurality of document formats such that a single report format document is generated. The report generator can further assign distinct markers or determine data markers within a document. The markers are preferably assigned manually by a user but can be automatically generated and assigned by the system.

A template 25 can be configured to communicate with at least one information architecture, a visual design or a conceptual structure. Other information may also be assigned to a template 25 which provides the necessary information for internet or online use. In a further embodiment, a report can be generated from an output received from an application or program not associated with the system.

In yet a further embodiment, there is provided a process for converting a spreadsheet into an internet application. The internet application is adapted to be suitable for consumption by consumers such as human users as well as automated agents (e.g., robotic internet services). The process includes the steps of: generating a first spreadsheet, or initial spreadsheet, which is preferably generated by a content creator or owner, generating a second spreadsheet, or modified spreadsheet, which is created based on at least one data set from the initial spreadsheet. A template engine, comprising at least one template is adapted to be associated with the modified spreadsheet. At least one data set is extracted from the modified spreadsheet by the template engine. A rendering interface can then adapt the extracted data set(s) for output and accepts inputs for processing. The rendering interface can interact with content consumers, preferably through client devices, such as a laptop, a smart phone, a cellular device, a computer or any other suitable device for displaying an output generated by the process, or through programmatic interfaces. Optionally, a client device may add to, modify, alter and/or delete at least one data set from the extracted data. Adding, modifying, deleting or altering data, can be processed by the rendering interface and template engine in real-time and any changes can be immediately made to the extracted data set. The template engine may also apply the changes made to the extracted data set in real-time back to the modified spreadsheet or optionally the initial spreadsheet. This allows for data to be bidirectional, which ensures more streamlined data processing and reduces delays caused by double handling data.

The initial spreadsheet is preferably stored in an environment which is at least one of a non-volatile storage medium and/or a cloud. Preferably, the client device is selected from at least one of the group of; a smart phone, a laptop, a computer, a mobile device, a tablet, and a personal digital assistant. Changes made to the extracted data set can be adapted to be recorded on the modified spreadsheet and also be recorded in the initial spreadsheet, after being recorded by the modified spreadsheet. Preferably, the render interface is adapted to render the extracted data set to generate an output. The output can be, for example, an internet application or webpage. The storage means is adapted to further store the output and any spreadsheet modifications desired to be saved by the user. The output is adapted to be dynamically resized for display on a client device. Preferably, the output is at least one of; a word document, a spreadsheet, a webpage, a website, a code, a script, an application, a PDF, a presentation, a slideshow, and a report. Preferably, the at least one data set includes at least one of; alphanumeric text, a formula, an equation, an algorithm, embedded data, graphs, charts, flow diagrams, images, audio data and video data.

In a further embodiment, parts of the process may be adapted to use the simple object access protocol (SOAP) to form the foundation layer of a service stack, which may provide a basic messaging framework for communication with automated agents such as web services. SOAP allows for exchanging data from a XML format into structured information for web services. SOAP typically uses at least one XML data set for a message format and allows another application to convert the data for message negotiation and transmission. Using SOAP, in the rendering interface for example, may allow for an output that is typically more security compatible with internet services or web services.

It will be appreciated that other internet protocols or formats in place of SOAP may be used to enable communication with automated agents. For example, the rendering interface and template engine may be adapted to generate output compatible with common protocols such as hypertext transfer protocol (HTTP) or simple mail transfer protocol (SMTP), and may accept input in these formats for editing purposes.

For example, a system implementation may be adapted to send a SOAP request to a server which has web services enabled with the parameters for a search. The server may then return the result, in an XML format, with the data retrieved from the search. The retrieved data preferably comes in a standardised machine-parsable format, such that the requesting system can then integrate the result as edits to the data set or spreadsheet documents.

In yet another embodiment, the template engines and rendering interfaces may be available to the content creator/owner for selection. This allows the content creator or owner a choice to select a desired template engine which enables the content creator/owner to control the content of the final output, while the choice of rendering interface enables the content creator/owner to control the format of the final output and the acceptance of appropriate inputs from content consumers. Preferably multiple number of template engines and/or rendering interfaces may be selected so that the output is consumable by a variety of different client devices. Optionally, a client device can be assigned to be served, or adapted to interact with, a suitable rendering interface and/or template engine. For example, at least one of the template engine and the rendering interface may be designed to support consumption by authorised web services and other automated agents. Alternatively, at least one of the template engine and the rendering interface may be suitability designed to support consumption by user agents, such as a web browser. Changes made via the client device to the extracted data set is recorded in real-time in the modified spreadsheet by the template engine; at a later time, the template engine may choose to propagate the changes made to the modified spreadsheet back to the initial spreadsheet.

Preferably, the extracted data set is at least one of; alphanumeric text, a formula, an equation, an algorithm, embedded data, graphs, charts, flow diagrams, images, audio data and video data. Preferably, the initial spreadsheet and modified spreadsheet comprises a plurality of data sets. Preferably, the output is adapted to dynamically resize on the client device with respect to a display means of the client device. Preferably, the output generated is at least one of; a word document, a spreadsheet, a webpage, a website, a code, a script, an application, a PDF, a presentation, a slideshow, and a report. Preferably, the server stored the output generated.

Referring to FIG. 4 , there is depicted a flowchart of a process 60 for generating an output, such as an internet application. A user, such as a content creator or a content owner, generates or uploads an initial spreadsheet 62 to a database or server. The user then selects an initial spreadsheet 64 which instantiated or converted into a modified spreadsheet 66. The modified spreadsheet is preferably in an XML, format, which may differ from the format of the initial spreadsheet. Both of the initial spreadsheet and the modified spreadsheet contain substantially the same data sets, if not the exact same data sets, and preferably only differ in document format. A template selected by a user 68 or a predetermined template is assigned at least one data set from the modified spreadsheet. The data assigned may be extracted cells 70, which have been highlighted, marked or otherwise selected and inserted into the template. The extracted data is formatted to be in a form suitable for rendering into an output and may accept additional inputs, either from another application, program or user input. The template arranges the data into a format which may closely resemble the final output, such as an internet application or internet webpage; it may also facilitate any modifications to the data at this point. Once the data has been extracted or assigned to the template and any modifications have been made by the user, a render interface or aggregator parses the data in the rendering interface 72 which generates a final output 74.

The final output may optionally be adapted to be modified by a user or an automated agent. Any modifications to the final output may generate a new data set which can be uploaded to the modified spreadsheet. This allows bidirectionality of at least one data set. Bidirectionality of data is advantageous as this reduces the potential for errors to be generated or may reduce the time to record data in both a spreadsheet and also an internet application format. It will be appreciated that for the data to be recorded into the modified spreadsheet, it optionally bypasses the template or the rendering interface steps. Alternatively, the rendering interface or template may convert or adapt the data to be in a format suitable to be recorded into the modified and/or initial spreadsheets. A further template or rendering interface may be used to allow bidirectionality of the data.

Alternatively, only newly added data or modified data prior to rendering is bidirectional, such that the final output cannot modify data contained in the modified spreadsheet or the initial spreadsheet. Preferably, a user may select from a plurality of templates and render interfaces. It will be appreciated that a plurality of initial spreadsheets may be selected to generate an output.

In another embodiment, there is provided a system 10 for managing families or chains of related spreadsheets. This system comprises a server including a non-transitory non-volatile storage medium. The storage medium is adapted to store the spreadsheets and store data sets extracted from the spreadsheets, and to store at least one template that is matched with at least one of the data sets to create at least one template instance. This system also comprises an aggregator that processes at least one template instance to produce output content for consumption on at least one client device. When a spreadsheet is modified, a copy of that spreadsheet is made forming an ancestor-descendant relationship among the two spreadsheets, and additional spreadsheets with such relationships forming a family branch or chain of related spreadsheets, their data sets may be merged to generate updated output adapted to be display on at least one client device. The spreadsheets from two family branches or chains can be merged to form a new combined family branch or chain, and related data sets may be merged to generate updated output adapted to be display on at least one client device.

Referring to FIG. 5 , there is depicted a simplified embodiment of the system 10 regarding from spreadsheet to web enabled output content: downstream information dissemination. The system 10 is adapted to receive multiple spreadsheets and store the spreadsheets in a storage device 30 that is part of a server 30. The spreadsheets can be uploaded by users or autonomous clients with authority to upload them to the system. Such users are considered content creators since they are responsible for creating the spreadsheets and managing their contents. In at least one embodiment, the server 30 includes a non-transitory non-volatile storage medium adapted to store the uploaded spreadsheets. The server 30 can also be a non-volatile memory medium, a cloud or any other suitable computer readable medium for storing electronic documents. The spreadsheets 20 may be in a standard spreadsheet format such as; .gnumeric, .ods, .xls, XMLss, comma-separated values, CVS application support, Data Interchange Format, Symbolic LinK (SYLK), Tab-separated values or any other spreadsheet format, which may include a derivative of any one of the previous formats. Another common spreadsheet format is “.xls” used by Microsoft Excel™. It will be appreciated that the system can be adapted for use with other known spreadsheet formats.

The system 10 is optionally adapted to group and analyse spreadsheets uploaded or associated with the server 30. Spreadsheets are grouped into baskets, where a basket can contain one or more spreadsheets. Analysing a spreadsheet can identify or extract data sets stored in the spreadsheet. A content creator may choose to extract multiple data sets from a single spreadsheet; extracted data sets stay within the basket of its originating spreadsheet. The spreadsheet may comprise raw data, formulas or equations associated with at least one cell. Data sets can be extracted from a spreadsheet by selecting elements within the spreadsheet.

For example, one mechanism for selecting elements is to ‘highlight’ the elements. An element can be; a spreadsheet cell, a cell range, alphanumeric text, a graph, a chart, an image, a pie chart, a bar graph, a line graph, a column chart, an area chart, a scatter graph or any other illustrative representation of data. Furthermore, element such as image, audio, hyperlink or video may be allowed. Highlighting an element preferably applies a viewable marker, such that content creators can visually identify which elements are used to construct the final data sets. A viewable marker may be at least one of; bolding text, changing a text colour, changing a cell colour, applying a border to a cell, a format change, stylising font, a font size alteration, or any other predetermined marker to allow content creators to determine a difference between a highlighted element and a non-highlighted element. This provides a means for a content creator to ensure that created data sets only contain desired data. Once a data set has been created, it is stored in server 30's storage medium; its association with the spreadsheet where it was created from is also stored.

The system 10 comprises a database which stores at least one template. A template plays an important role in the process that transforms data sets into output content. Templates are created and uploaded to the system by users referred to as template creators. A template defines sections or elements that are like receptacles for data, which are intended to be matched with data elements from one or more data sets extracted from spreadsheets. A template also contains rules that are used to transform the received data in a desired manner or in a predetermined format decided by the template creator.

Related rules within a template are grouped together to form an output profile. Several output profiles may exist within a template, and each output profile is targeted to produce output content for consumption on specific client devices. Preferably, a client device is at least one of the groups of; a smart phone, a laptop, a computer, a mobile device, a tablet, and a personal digital assistant. Hence, a single template may have multiple device-specific output profiles, and different profiles are typically designed to generate different output content optimized for consumption on different client devices. For example, one output profile may be optimized to create output content for display on a tablet web browser to human users, while a different output profile may be optimized to create output content for consumption by automated agents such as robotic internet services.

The action of matching a template's elements with data from data sets results in the creation of a template instance. The data sets may also be said to have been assigned to that particular template to form the template instance. In one representation, a template instance may consist of a copy of the original template and multiple assigned data sets. Template creators are expected to work closely with content creators to develop templates that will output the most informative and expressive content for a particular set of spreadsheets. Hence, template creators are also responsible for assigning appropriate data sets to the templates that they have created. After a template is uploaded to the system, it is placed within the same basket as the spreadsheets and data sets that the template is intended to be matched with. A template may then be assigned one or more data sets extracted from one or more spreadsheets within the same basket, and the resulting template instance is also placed in the same basket. Template instances are sent to an aggregator component for further processing to produce output content.

An aggregator component processes template instances as input and produces output content for consumption by end-users referred to as content consumers. For each template instance, the aggregator applies the relevant output profile rules on the template instance data sets to produce output content for a specific client device. The aggregator may have predetermined settings that select the appropriate output profiles based on the client devices used by content consumers. For example, if a template instance contains data sets, rules and output profiles suitable to support the creation of a web page and the client device has a web browser, then the aggregator will use these elements to render output content on a client device in the form of a web page. The aggregator will merge or aggregate all output content from template instances from the same basket to generate a unified output content for consumption. For example, if multiple template instances from the same basket each produce a single web page, then the aggregator will compile the web pages together to form a web site with multiple web pages. The nature of the output content produced by the aggregator is dependent on the output profiles of the template instances processed. The aggregator itself may also possess codified rules that determine how various output content may be merged to form a unified output content.

Preferably, output content from the aggregator is at least one of; a word document, a spreadsheet, a PDF, a presentation, a slideshow, a report, a code, a script, a web page, a web site, an application, a web interface, a smartphone or a tablet interface or any other suitable online format which can preferably be hosted by a web domain. The content can comprise interactive features, such as audio, video, interactive graphs, input fields, dropdowns, lists, or any other predetermined interactive feature that may allow editing of the content to be achieved. Preferably, the content is adapted to dynamically resize or scale based on a content consumer's consumption device with respect to a display means of the device. For example, for content in the form of web pages, the pages are preferably adapted to be displayed on a plurality of display sizes such as a desktop computer monitor screen and a portable smart phone device screen. Resizing or scaling the output content from the aggregator may include adjusting the vertical and/or the horizontal alignment of the page. Further, the content can be adapted to move or resize individual elements on a web page to generate a format which is more visually appealing or more user-friendly.

A central capability of system 30 is to disseminate information expressed by content creators to content consumers via spreadsheets and output content. The flow of information from content creators to content consumers may be considered to be the norm, so for ease of discussion this direction of flow will be called the downstream flow of information. The next section will explain how updates and changes to the information may be communicated back in an upstream direction from the content consumer to the content creator.

Referring to FIG. 6 , the process of the upstream flow of information updates of the system 10 is illustrated. When interactive output content is generated from the aggregator for consumption on client devices, content consumers can interact with the content and make edits to the content. A series of related edits are grouped into an edit session, which may preferably correspond to a web browser session or a user login session. As illustrated in FIG. 6 , edits made by content consumers transmit changes or updates from content consumers back to content creators in an upstream direction. Every edit operation results in a signal being sent from the client device to the aggregator, which in turn applies rules in the corresponding template instance to enact changes to one or more data sets assigned to the template instance, the nature of the changes are determined by parameters of the edit operation. The first change to a template instance's data set will result in the creation of a modified data set, so that the original data set is not itself modified. Further changes caused by subsequent edit operations from the same edit session will apply updates to the new modified data set. Additionally, edit sessions are permanently recorded in server 30; and the link between a modified data set and the edit session that created it is also preserved. Consequently, content consumers have the ability to scatter edits in an edit session over a number of days, months or even years.

As illustrated in FIG. 6 , if multiple content consumers are to make edits in separate edit sessions, then multiple modified data sets will be created and updated, each linked to the edit session of the content consumer that made the edits. The figure also shows that when an edit is made to unified output content produced from a basket A containing two template instances A1 and A2, two modified data sets may be created because the unified output content is an aggregate of output contents from the two template instances of basket A. As a result, a single edit operation may in general result in the creation and/or update of multiple modified data sets, one for each of the template instance data sets contained within a single basket.

Modified data sets can be merged with related spreadsheets from the same basket to form modified spreadsheets, where data elements from the modified data set have replaced the original data elements in the modified spreadsheets. This is possible because data elements in the modified data set correspond to elements in the unmodified data set, which in turn have been extracted from elements within the original unmodified spreadsheet. As shown in FIG. 6 , the existence of modified spreadsheets is useful because content creators may wish to download modified spreadsheets from the system to see the changes that have been made by content consumers compared to the original spreadsheets.

While it may be appropriate to store modified spreadsheets permanently in server 30, it may also be advantageous to reduce the longer term server storage needs by storing modified spreadsheets temporarily before destroying them. At any time, a modified spreadsheet can be created on demand, for example, in response to a download request by a content creator. Creating a modified spreadsheet will involve taking the corresponding unmodified spreadsheet and merging it with the relevant modified data sets from the same basket. For each edit session, multiple modified spreadsheets may be created over time, for example, as records of changes made in the edit session.

At this point, it has been explained how system 30 manages the downstream dissemination of information from content creators to content consumers as well as the upstream communication of changes or updates to the information from content consumers to content creators. The next section will explain how system 30 achieves the downstream flow of changes or updates from content creators to content consumers.

Referring to the downstream flow of updates of the system 10, modified spreadsheet, in addition to being downloaded by content creators, can also be used to update modified data set elements that have not been edited directly by a content consumer. Consider an example where a content creator has developed a simulation of some kind in a spreadsheet, system 30 may then communicate this simulation to a content consumer as a web site. In an edit session, the content consumer may change a parameter that represents the initial condition of the simulation. This will prompt the creation of a modified data set. A modified spreadsheet can then be created from the modified data set, incorporating the changed initial condition. Formulas and calculation rules in the modified spreadsheet may then trigger a cascade of updates resulting in changes to simulation results in addition to the updated initial condition. Data elements representing the simulation results from the modified spreadsheet can then be used to update corresponding data elements in the modified data set. Consequently, the modified data set can now hold updated values not only for the initial condition of the simulation, but also the updated simulation results; even though the content consumer did not make any direct edits to the simulation results. Modified spreadsheets are stored in the system temporarily before being removed automatically, although they may be saved permanently if requested by the content consumer, for example, as a means to record a snapshot of changes made in an edit session.

As a modified data set is continuously updated in an edit session, it will also cause related output content from the aggregator to be constantly updated. When processing a template instance, the aggregator will replace unmodified data sets in the template instance with corresponding modified data sets linked to the relevant edit session. Consequently, output content produced by the aggregator will incorporate changes that have resulted from edits in the relevant edit session. With constant updates, the output content will continuously reflect changes in the modified data set in real time, which in turn is in response to edits made by the content consumer.

FIG. 7 refers to the branching of multiple updates. The top left of FIG. 7 illustrates an initial situation where a basket contains spreadsheet 1 and data set 1. The basket also contains modified data set 1 created by edit session A belonging to a content consumer A. After some time, a content creator C may decide to update spreadsheet 1, say, to make corrections to calculation mistakes discovered in the spreadsheet. The updated spreadsheet 1 when uploaded to server 30 becomes spreadsheet 2 in a new basket; this is so that spreadsheet 1 itself is never modified. From spreadsheet 2 the system extracts data set 2, which will very likely contain differences when compared to data set 1. To take advantage of the calculation corrections made by the content creator C and keep the changes from edit session A, content consumer A can upgrade the modified data set 1 associated with their edit session A. This is illustrated in the figure by the upgrade path from modified data set 1 to modified data set 2. Modified data set 2 is created as a result of the upgrade and it is stored in the same basket as spreadsheet 2 and data set 2. Modified data set 2 preserves changes that are in modified data set 1 (compared to data set 1) while also sources data elements from data set 2 so that it includes both edits made in edit session A as well as the calculation corrections contained in spreadsheet 2.

Generally, upgrade of modified data sets may not be straightforward, so the system optionally allows a content creator to upload an upgrade spreadsheet to help with the upgrade process. Upgrade spreadsheets contain rules and calculations that specify how to transform data from one modified data set to another. FIG. 6 illustrates the use of upgrade spreadsheet 1-2 to transform modified data set 1 into modified data set 2.

Since modified data set 2 is created as a consequence of upgrading from modified data set 1, it is initially not linked to any edit session. At a later time, the system can present to a content consumer the option to start a new edit session from an existing modified data set. An example is illustrated in FIG. 6 where a new content consumer B begins an edit session B by linking it with modified data set 2. Starting a new edit session B from modified data set 2 means no new modified data set is created and that content consumer B need not repeat the edits made earlier by content consumer A in edit session A because modified data set 2 already includes changes resulting from edit session A. Additionally, content consumer B will see that output content in edit session B reflects the calculation corrections introduced by content creator C in spreadsheet 2 because modified data set 2 is associated with data set 2. Note that while the example illustrates content consumer B starting edit session B, it will be appreciated that the system allows any content consumer to have started edit session B, not just content consumer B.

After some additional time, a content creator D may decide to upload another revision of spreadsheet 1 to the system as spreadsheet 3. Spreadsheet 3 may contain differences when compared to spreadsheet 2, perhaps content creator D has added new content to spreadsheet 3 that is not in spreadsheet 2. FIG. 6 shows the case where the number of data sets extracted from spreadsheet 3 has increased to two as a reflection of the newly added content. Content consumer A has now a new upgrade path from modified data set 1 to modified data sets 3. This upgrade path involves upgrade spreadsheet 1-3, which must take into account the input having only one modified data set (modified data set 1) while the output consists of two modified data sets (modified data sets 3). Upon creating modified data sets 3 by upgrading from modified data set 1, a content consumer can then start a new edit session from modified data sets 3 to take advantage of the new content added by content creator D.

FIG. 8 illustrates the process of merging different branches of the system 10. Consider the state illustrated in FIG. 7 with the presence of spreadsheet 1, spreadsheet 2 and spreadsheet 3. It can be appreciated that spreadsheet 1 can be considered to have a parent-child relationship with spreadsheet 2 and spreadsheet 3, while spreadsheet 3 can be considered to be a branch of the family in relation to spreadsheet 2. FIG. 8 continues from FIG. 7 and illustrates the upload of spreadsheet 4 by content creator C that further revises spreadsheet 2. Spreadsheet 1 and spreadsheet 4 can then be considered to have an ancestor-descendant relationship, hence forming a family branch or chain of related spreadsheets.

Sometime later, content creator D may make updates to spreadsheet 3, not only to enhance contents in spreadsheet 3 but also to incorporate calculation corrections and other revisions made in spreadsheet 4. Content creator D is then able to upload a new spreadsheet 5 to server 30 as shown in FIG. 8 , and mark it as a revision of both spreadsheet 3 and spreadsheet 4, thereby merging the two branches represented by spreadsheet 1-spreadsheet 3 and spreadsheet 1-spreadsheet 2-spreadsheet 4. In the general case, the tips of two spreadsheet branches, or the most recently uploaded spreadsheets from two branches, may be merged to form a combined branch.

Suppose that content consumer B has created edit session B and would like to receive the benefits of the updates made in spreadsheet 5 and to keep the changes made in edit session B. It is then necessary for him to upgrade the modified data set 2 associated with his edit session B. FIG. 8 illustrates the path that such an upgrade will take, which is to first make use of upgrade spreadsheet 2-4 to transform modified data set 2 into modified data set 4. Next, the upgrade continues by transforming modified data set 4 into modified data sets 5 with the help of upgrade spreadsheet 3-4-5. The upgrade ends with the creation of modified data sets 5. Note that since edit session B is only linked to modified data set 2 in this example, the use of upgrade spreadsheet 3-4-5 does not involve any modified data sets associated with data set 3 because none is associated with edit session B. Note that since modified data sets 5 is upgraded from modified data set 4, and that modified data set 4 is upgraded from modified data set 2, it follows that modified data sets 5 may incorporate changes captured in modified data set 2. Modified data sets 5 may also incorporate changes captured in modified data set 1 because modified data set 2 is upgraded from modified data set 1.

Suppose that content consumer B has created another edit session C in addition to edit session B and would like to receive the benefits of the updates made in spreadsheet 5 and to keep the changes made in both edit session B and edit session C. The upgrade path, as shown in FIG. 7 , will first make use of upgrade spreadsheet 2-4 to transform modified data set 2 (linked to edit session B) into modified data set 4. Next, the upgrade continues by transforming modified data sets 3 (linked to edit session C) and modified data set 4 into modified data sets 5 with the help of upgrade spreadsheet 3-4-5. In this example, modified data sets 5 will incorporate data elements in both modified data sets 3 and modified data set 4. Hence the modified data sets 5 in this example are different to the modified data sets 5 from the previous example, which incorporated data elements in modified data set 4 only. Once the upgrade process ends and modified data sets 5 has been created, content consumer B (or any other content consumer for that matter) can start a new edit session D from modified data sets 5 to take advantage of the latest updates made by content creator C in spreadsheet 4 and content creator D in spreadsheet 5.

Due to the likelihood of significant divergent changes between spreadsheet 3, spreadsheet 4 and spreadsheet 5, as well as possible conflicting differences in data elements and their values between the associated data sets and modified data sets, it may not be possible for upgrade spreadsheet 3-4-5 to successfully transform the multiple input modified data sets into modified data sets 5. In cases where upgrade is not possible or fails due to conflicts or inconsistencies in input modified data sets, the content consumer that initiated the upgrade will be offered control of the upgrade so that he may manually resolve any conflicts and inconsistencies that exist. Alternatively, the content consumer may choose to abort the upgrade and instead begin a new edit session that creates a new modified data set from an unmodified data set and repeat his previous edits again.

When a content consumer triggers an upgrade of a modified data set, the upgrade process does not prevent the modified data set from receiving further updates from its linked edit session. For example, a successful upgrade of modified data set 2 and modified data sets 3 to modified data sets 5 in FIG. 8 does not prevent content consumer B from making further edits in edit session B. In fact, content consumer B may go back to edit session B to make changes even after having spent time in edit session D. In general, content consumers have the option to revisit and continue with their edit sessions at any time.

Furthermore, the system enables a content consumer to initiate upgrade on the same modified data set multiple times while having made edits that change the modified data set in between each upgrade. Resulting modified data sets created by upgrades from the same source modified data set will likely contain similarities and differences compared with each other—in fact they can be considered versions of each other. For example, the first time modified data set 2 in FIG. 7 is upgraded, the output of transformation may be better denoted as modified data set 4.1 to indicate that it is the first version of the upgrade result (namely modified data set 4). If modified data set 2 is later upgraded a second time, perhaps after receiving further edits, then the result may be denoted modified data set 4.2 to indicate that it is the second version of modified data set 4. Generally, there can be many versions of modified data sets that exist as a result of repeated upgrades. All versions of modified data sets are stored on server 30 unless explicitly discarded by the content consumer who initiated the upgrades.

Note that the spreadsheet branches and the accompanying upgrade paths shown in the figures and discussed so far are for illustration purposes only and the system in general is in no way restricted to these branches and paths only. It will be appreciated that in general many branches and paths are possible in addition to those already discussed. For example, one possible branch merge based on FIG. 8 that has not been mentioned is a new spreadsheet that revises spreadsheet 2 and spreadsheet 3.

This section has explained how system 30 achieves the downstream flow of changes or updates from content creators to content consumers. Supported by system 30, content creators are able to flexibly distribute updates to their spreadsheet contents to content consumers through multiple spreadsheet revisions. At the same time, the system enables content consumers to receive the updated spreadsheet contents without having to repeat the edits they have already done in their edit sessions.

The system 10 has the following advantages over the prior art systems:

-   -   Ability to produce output content in a variety of         internet-enabled formats for consumption based on spreadsheet         data. So only knowledge of spreadsheets is required for content         creators to develop content for consumption over the internet.     -   Output content can be interactive and may allow editing so as to         produce changes in output content in response to content         consumer inputs in real time.     -   Can easily make updates and corrections to output content by         uploading new revisions of a source spreadsheet.     -   Uploaded spreadsheets are not directly modified, so they are         preserved as a historical record of modifications, which enables         the system to offer features equivalent to a version control         system for spreadsheets. Content creators can trace the history         of the changes they've made.     -   Using different templates, a single spreadsheet can be used to         produce a variety of output formats, including interactive         formats that allow real time edits and update to the output         content.     -   Edits result in the creation of modified data sets. At any time,         modified data sets associated with a spreadsheet can be merged         with the original spreadsheet content to form a modified         spreadsheet, which captures the edits in the form of a         spreadsheet. This enables the sharing and publication of the         edits in a portable and easily understandable format, useful for         use cases such as audits and validations.     -   Edits result in the creation of modified data sets, which can be         updated through migration to take advantage of updates to the         original spreadsheet, for example, to fix calculation errors.
